High-Precision Industrial Control PCBA OEM Customization and Processing

　　Deeply engaged in the core electronic manufacturing needs of the industrial control field, we focus on providing high-precision, high-reliability, and high-stability PCBA OEM customization and processing services. Relying on a professional industrial-grade manufacturing system, strict quality control standards, and customized technical solutions, we adapt to various industrial control equipment such as PLCs, inverters, servo controllers, industrial sensors, and CNC systems, helping enterprises improve the performance of core control components and ensuring the precision, efficiency, safety, and stability of industrial production processes.

　　Core Competitiveness: Adapting to the Rigorous Requirements of Industrial Control

　　1. High-Precision Manufacturing Process, Laying a Solid Foundation for Control Core

　　Adopting high-precision SMT placement equipment, we support the accurate placement of 0201 micro-components and complex packaged devices such as BGA, QFP, and LQFP, with a placement accuracy of up to ±0.03mm, meeting the high-density and miniaturization design requirements of industrial control PCBA. For industrial-grade PCB substrates (FR-4 high Tg material, metal substrates, etc.), we match lead-free high-temperature reflow soldering technology and zone temperature control technology to ensure solder joint strength and conductivity, effectively improving the stability of PCBA during long-term high-frequency operation and reducing failure rates. Equipped with a triple quality control system of SPI (Solder Paste Inspection), AOI (Automatic Optical Inspection), and X-Ray inspection, we comprehensively inspect defects such as solder paste offset, cold soldering, and bridging, with a solder joint qualification rate of ≥99.99%.

　　2. Industrial-Grade Anti-Interference and Reliability Enhancement Solutions

　　Aiming at complex industrial on-site environments such as strong electromagnetic interference, high and low temperature fluctuations, and humidity and dust, we provide customized reliability enhancement solutions. In the PCB design optimization stage, professional engineers conduct DFM/DFMEA reviews, optimize grounding design, power supply layout, and signal isolation schemes to improve electromagnetic compatibility (EMC) capabilities; select industrial-grade components (wide temperature range -40℃~85℃, high surge resistance, long service life), strictly implement IQC (Incoming Quality Control) incoming inspection, and eliminate the mixing of consumer-grade components; can perform conformal coating treatment on demand to achieve moisture-proof, anti-corrosion, and dust-proof protection, ensuring the long-term stable operation of PCBA in harsh industrial environments.

　　3. Full-Process Customized Services, Adapting to Diverse Scenario Needs

　　Relying on a professional technical team, we provide full-process customized services from demand communication, scheme design, prototype sampling to mass production. For different industrial control scenarios (such as intelligent manufacturing, power control, rail transit, petrochemical industry, etc.), we accurately match technical parameters and process requirements: support small-batch customization (10-500pcs) to quickly respond to new product R&D verification needs; have mass production capacity (100,000+pcs) to ensure delivery efficiency through flexible production lines; can undertake special process needs, such as high-precision DIP insertion, manual soldering (for special packaged devices), functional modular assembly, etc., fully adapting to diverse customized scenarios.

　　4. Full-Link Quality Control and Traceability, Ensuring Product Compliance

　　Establish a full-link quality management system that meets industrial manufacturing standards, and strictly implement the four-level quality control process of IQC (Incoming), IPQC (In-Process), FQC (Final), and OQC (Outgoing). Equipped with a professional FCT (Functional Circuit Test) laboratory, we can customize test fixtures according to customer needs to complete power-on testing, signal transmission testing, load testing, long-term aging testing, etc., ensuring that each batch of PCBA meets design specifications. Relying on the MES (Manufacturing Execution System) production management system, we realize "one product, one code" full-link traceability, accurately recording component batches, production equipment, operators, test data and other information, ensuring product traceability and compliance, and adapting to the strict quality audit requirements of the industrial field.

　　Applicable Fields: Covering the Full Range of Industrial Control Equipment

　　Our services cover a full range of industrial control equipment, including intelligent manufacturing equipment (PLCs, servo drives, stepper controllers), power electronics (inverters, converters, charging pile control boards), rail transit control equipment, petrochemical monitoring and control modules, CNC machining center control systems, industrial sensors (temperature, pressure, displacement sensor control boards), and automated assembly line control units. We have provided customized PCBA OEM services for hundreds of mid-to-high-end industrial control enterprises, and our products are widely used in core fields such as intelligent manufacturing, new energy, rail transit, and high-end equipment manufacturing.
